Here’s a real time-saver. If you ever needed to rename or enumerate a bunch of files, and have been manually doing it up till now, then this is the program just for you. Ant Renamer is full of common actions you might have run into when dealing with larger amounts of files, such as photos of a vacation or frames of an animation.

You can add characters, search and replace strings, use the file date for its name, use EXIF information, or even run a regular expression on your file list. It displays what the output will look like at the bottom as a preview. Finally, there’s an Undo button if you make a mistake.

Check it out next time you have some heavy renaming to do. It’s freeware and even includes source code or translation files if you’re inclined to start modifying it.
